In reviewing a patient’s complete blood count (CBC) results, the nurse notes a "shift to the left." What is the significance of these results?
There is an elevated number of immature thrombocytes.
There is an elevated number of immature neutrophils (bands),
There is an elevated number of mature neutrophils (segs)
There is an elevated number of mature erythrocytes
The Correct Answer is B
A. There is an elevated number of immature thrombocytes - Thrombocytes are platelets, and a shift to the left does not refer to these.
B. There is an elevated number of immature neutrophils (bands) - A "shift to the left" typically refers to an increase in immature neutrophils, also known as bands, in the blood. This often indicates an acute infection or inflammation as the body is producing and releasing more neutrophils to fight an infection.
C. There is an elevated number of mature neutrophils (segs) - An elevated number of mature neutrophils (segmented neutrophils) does not indicate a shift to the left. The term specifically refers to immature forms.
D. There is an elevated number of mature erythrocytes - Mature erythrocytes are red blood cells, and a shift to the left does not pertain to red blood cell counts or maturity.

Correct Answer is A
Explanation
A. Exposure to radiation - Exposure to high levels of radiation is a known risk factor for developing CML. Historical data, such as from atomic bomb survivors, show a higher incidence of leukemia, including CML, among those exposed to radiation.
B. Family history - CML is generally not associated with a significant familial risk. It is more commonly linked to acquired genetic mutations rather than inherited predispositions.
C. Another type of cancer - Having another type of cancer does not directly increase the risk of developing CML. However, treatments for other cancers, like radiation therapy, might increase risk.
D. Genetic mutation - The development of CML is associated with a specific acquired genetic mutation known as the Philadelphia chromosome (translocation between chromosomes 9 and 22), rather than inherited genetic mutations.
Correct Answer is ["A","C","E"]
Explanation
A. D-dimer blood test - A D-dimer test measures clot breakdown products in the blood. Elevated levels suggest the presence of an abnormal blood clot, such as in PE, although it is not specific.
B. Complete blood count (CBC) - A CBC is not typically used to diagnose PE. It may be ordered to check for other conditions or as part of the overall health assessment, but it doesn't confirm PE.
C. CT scan - A CT pulmonary angiography is the gold standard for diagnosing PE. It provides detailed images of the blood vessels in the lungs.
D. Chest x-ray - A chest x-ray is not diagnostic for PE. It is often performed to rule out other causes of the client’s symptoms (e.g., pneumonia, pneumothorax) but does not confirm the presence of a pulmonary embolism.
E. Lung ventilation and perfusion scan (VQ scan)
A VQ scan is another diagnostic tool for PE, especially in clients who cannot tolerate contrast dye required for CT scans. It assesses the ventilation and perfusion of the lungs and identifies mismatches suggestive of PE.
